Aim of Study: The present study was planned to analyze serum heme oxygenase-1 levels in osteosarcoma patients. Materials and Methods: Twenty five histopathologically confirmed cases of osteosarcoma localized without metastasis of all the ages attending the Orthopedic Clinics were included in the study group and twenty five patients having musculoskeletal pain (age and sex matched) served as control. Five ml of venous blood was collected aseptically from antecubital vein and serum was be separated by centrifugation and analyzed the same day. Routine biochemistry investigations were performed as per standard enzymatic methods by autoanalyzer. Serum Heme oxygenase-1 was analyzed by enzyme-linked immunosorbent assay. Results: In osteosarcoma patients, serum HO-1 levels were increased as compared to patients having musculoskeletal pain (P < 0.05). Workers have found that HO-1 induction in prostate cancer cell lines (PC3) cells restored the proliferation of osteoblasts, which was inhibited during co-culture with parental prostate cancer cell line PC3 cells. However, no concrete data are available on blood levels of HO in osteosarcoma. Major role of HO-1 is the protection against oxidative injury, additionally, it regulates cell proliferation, modulates inflammatory response and facilitates angiogenesis. Conclusion: Findings of the present study suggests that pharmacological agents that regulate HO activity or HO-1 gene silencing may become powerful tools for preventing the onset or progression of various cancers and sensitize them to anticancer therapies.
